Why Does Answers Run Code in 2025a But the Run Button, the "Executing In" Popup, and the "Ran In" Tag Still Show 2024b?

We are now back to the same problem. Back end in 2025b, front end shows 2025a

matlabRelease

ans = 
  matlabRelease with properties:

    Release: "R2025b"
      Stage: "release"
     Update: 1
       Date: 05-Sep-2025

Now running R2025b Update 2, but still showing Ran In: 2025a

matlabRelease

ans = 
  matlabRelease with properties:

    Release: "R2025b"
      Stage: "release"
     Update: 2
       Date: 16-Oct-2025

@Paul, I'll look into it.

Answer 1

[Walter Roberson]

This is a known issue. The "back-end" was upgraded to R2025a, but for some reason the "front-end" was not upgraded.

[Matt J]

I hope they will be able to fix this reotroactively. Otherwise, the Answers forum will be tainted with false documentation of how R2024b behaved.

[Tushal Desai]

We'll be upgrading the front-end to R2025a very soon which should then reflect the true backend and the run banners will then show R2025a.

[Matt J]

@Tushal Desai but will this apply retroactively to pre-existing posts, or only to new posts?

[Tushal Desai]

Only to new posts once the front end (editor) is updated. We can retroactively update existing ones but it may take some time. Will update here once we have some timeline I can share.

[Paul]

Looks like the front end has been updated. @Tushal Desai

[Tushal Desai]

Yes, we updated it on 4th Sept. And there is a plan to soon retroactively update pre-existing posts prior to this front end update to change the 'Ran in' version to reflect the true backend version.
